SELF-CLOSING FAUCET.

Specification of Letters Patent.

Patented July 2,1918.

Application filed September 20, 1915. Serial No. 51,721.

To all whom it may concern:

Be it known that I, Fnnn Summer, a citizen of the United States, residing at Cleve land, in the county of Cuyahoga and State of Ohio, have invented certain newand usei'ul Improvements in self-Closingl aucets,

of vwhich the followingis a specification.

, This invention relates-to an improvement in self closing; faucets, and the improvement involves the asset? trunnion rollers i11 tel-posed between two members of the faucet, and also, the employment of a single stamp ing of sheet metaliormed'in a particular way to separate the rollers and to secure them so that the device may be readily as sembled and disassembled, allsubstantially as herein shown and described and more par ticularly pointed out inthc claims.

In the accompanying drawings, Figure 1 is a side elevatiornpartly in section, of a self-closing faucet embodyingimy improvez I Pig. 2,

went. Fig. 2 is a plan view, full size, ofthe rollers and retainer used in said faucet.

and Fig. 4: is a side view thereof. Fig. 5 is an enlarged view of the'sheet metal retainer u'ith the-rollers removed, and Fl a cross section on line (P-6, Fig. 0.

Fig. 3 is a sectional view on line Flg.

7 is a bottom view'ot Fig. F igs/S and the solid rollers.

'The invention is shown in Fig. 1 as'incorporated in a self-closingfaucet2,having a bonnet 3 surrounded by a rotatable handle .4, the upper and bottom surfaces of the honnet and handle being provided, vvith reversely-inclined bearing surfacesb'and 6, respectively, for, the, rollers 7 interposed therebetween. Three rollers '7 are used at equi-distant points radially of the valve stem to raise the valve against the tension of a strong spring8, shown in dotted lines rollers is limited,rollers having shorter axes than their diameters are preferably used. Moreover, as the pressure of the spring 8 is relatively great under maximum tension the use of solid or trunnion rollers is eX- ceedingly desirable to avoid breakage. It is advantageous also to secure the rollers in a suitable retainer 9, and particularly in such a Way that all the rollers may be jointly handled With the retainer when assembling 9 are section and sideviews of one of and disassemblin the faucet, and also so that each roller may he easily removed and replaced in the retainer. For these reasons I make the retainer 9 of sheet metal, prefer ably brass having spring properties. and form three rectangular openin s 10 at equidistant points radially in the body thereof, and also form the outer portion ot the body opposite each opening 10 downwardlydnto a flange 11 at right angles. In forming the openings 10 partof the stock is retained to round the upper edge of flange 11 and to. project the same above the plane of the body, thereby permitting ,a round aperture 1 12 to be formed in the flange substantially inv the same plane as the body.- A. second, downwardly-projecting flange 13, is 'also produced parallelingflangcflll but at thev opposite side of opening 10. Flanged?) is also provided with an aperture l t correjspondingly located to that o l-aperture 12, and the rollers 7 have trunnions 15 at each side adapted to be loosely-confined in said apt-n-tures, and also to be detachably en-- gaged with the flangesll and 13 which poS- sess suilicient spring to be flexed to. one side for, that purpose. The central ortionof the body of the retainerispunc ed outat its center to provide a round flanged opening 16 which is of larger diameter in the plane of the body than is the flange portion'lT thereof, thereby a tfording clearance between the valve stem and the dowmvardly-project ing flanges 13 and guarding againstcontae't ot' the roller trunnion ends with the valve stem. The inclines 51011 thebon iet 3 Inust also be cleared by the outer flanges 11615 the retainer, and thereforethe end portions ,18

"of said flanges are rounded'or tapered and formed at an angle to the main face thereof, and the retainer body is also cut out or serrated at 19 between the flanged portions 18 to provide clearance and non-interference with the crest portions of the inclines.

Tapering the end portions 18 of the flanges 11 strengthens the flange and the retainer body, thus safe-guarding accidental displacement of the rollers from the retainer. A substitute for the solid roller having integral trunnions, would be a roller having a solid pin driven or inmovably aflixed therein and projected on opposite sides thereof. Openings 10 are shown as rectangular, but

this fornr of opening'could he made o'tlier- Wise, particularly Where the roller was of different form than here shown; WhatI claim is: 1
